New Revision: 311757
URL: https://svnweb.freebsd.org/changeset/base/311757
Log:
Similar to r311750, check for the result from smiGetModule to avoid a segfault
when dereferencing a NULL pointer later on.
Choose to just check for the NULL pointer in the next for-loop for now to fix
the issue with a minimal amount of code churn
sys/queue.h use here would make more sense than using a static table
